Kentsfield is the code name of the first Intel desktop Core 2 Quad and quad-core Xeon CPUs, [1] released on November 2, 2006. The top-of-the-line Kentsfields were Core 2 Extreme models numbered QX6x00, while the mainstream Core 2 Quad models were numbered Q6x00. All of them featured two 8 MiB L2 cache. The mainstream 65 nanometer Core 2 Quad ...
A Core i7 940 system running at stock clock rates has obtained a 3DMark Vantage benchmark CPU score of 17,966. [13] A Core i7 920 system scored 16,294 running at stock clock rates. An Intel Core 2 Extreme QX9770, a very expensive member of the previous generation of Intel processors (costing over four times the price of the 920 at its launch ...
The latest badge promoting the Intel Core branding. The following is a list of Intel Core processors.This includes Intel's original Core (Solo/Duo) mobile series based on the Enhanced Pentium M microarchitecture, as well as its Core 2- (Solo/Duo/Quad/Extreme), Core i3-, Core i5-, Core i7-, Core i9-, Core M- (m3/m5/m7), Core 3-, Core 5-, and Core 7-branded processors.
With the release of the Core 2 processor, the abbreviation C2 has come into common use, with its variants C2S (the present Core 2 Solo) C2D (the present Core 2 Duo), and C2Q, C2E to refer to the Core 2 Quad and Core 2 Extreme processors respectively. C2QX stands for the Extreme-Editions of the Quad (such as QX6700, QX6800, QX6850).
Because of these problems, synthetic benchmarks such as Dhrystone are now generally used to estimate computer performance in commonly used applications, and raw IPS has fallen into disuse. The term is commonly used in association with a metric prefix (k, M, G, T, P, or E) to form kilo instructions per second ( kIPS ), mega instructions per ...
The useful work that can be done with any computer depends on many factors besides the processor speed. These factors include the instruction set architecture, the processor's microarchitecture, and the computer system organization (such as the design of the disk storage system and the capabilities and performance of other attached devices), the efficiency of the operating system, and the high ...

The actual performance will always be lower than the peak performance. [2] The performance of a computer is a complex issue that depends on many interconnected variables. The performance measured by the LINPACK benchmark consists of the number of 64-bit floating-point operations, generally additions and multiplications, a computer can perform ...
